Elliott was talking about their two-man advantage for 1:14 late in the third period, but the Ducks also put on an impressive display of penalty killing.
"We had a couple of clears, off the faceoff was big," Ducks defenseman Kevin Bieksa said. "Then we had a couple of clears after that. Anytime you can get the puck down the ice, all of sudden they're coming back and trying to get zone entry and it limits their opportunities to make plays."
Ducks goaltender John Gibson fought his way through a ragged performance but was sharp when he needed to be late in the game. "As the game went on, I felt better," he said.
Said Bieksa: "[Gibson] battled tonight. There were some chances there where he was on his knees and sprawling and made some big saves.
"You need those from your goalie. You need those for wins. There's a lot of little plays like that that define the outcome of the game. He's got to be good for us to have a chance."
The Ducks are getting terrific service on their first power-play unit, from Silfverberg, who was having an excellent night even before he scored the game-winning goal. But Silfverberg also believed the turning point came on the Flames' botched line change, because the momentum had been shifting away from Anaheim at that point.
"That was a big moment for us, and it swung our way," he said. "It was a bit of a lucky break, but that's what happens in playoffs. It's things like that that can turn a game around, and it did tonight."
